Frequently Asked Questions

What is FRP?

FRP stands for Fiber-Reinforced Polymer. It is a composite material made of a polymer matrix reinforced with fibers such as glass, carbon, or aramid. It offers high strength, corrosion resistance, and lightweight properties.

Where are FRP products commonly used?

FRP is widely used in chemical processing, marine, water treatment, power generation, offshore platforms, and industrial walkways due to its durability in corrosive environments.

Are FRP gratings slip-resistant?

Yes. Our FRP gratings come with a standard aluminum oxide grit surface or molded-in abrasive top layer for excellent slip resistance, even in wet or oily conditions.

Can FRP products be customized?

Absolutely. We offer custom pultruded profiles, grating sizes, handrail configurations, and molded parts to meet specific project requirements.

Do you provide international shipping?

Yes. NTWellGrid exports to customers worldwide, with reliable logistics and documentation support.
